The constructions of the F-respresentable matroid Q6 and W4 are investigated.The cycle matroid M(G) of G is charactered by the chain-group F0(G,R) on E(G) over R,and the matroid M' is obtained by relaxing the circuit-hyperperplane X of the matroid M.It is proved that M(K4) and M(W4) can be respresented by chaingroup and Q6 is construct by relaxing the circuit-hyperplane.W4 is constructed by M(W4) and the field F that W4 is representable is obtained.
